Abstract

A device is provided that issues a vehicle speed signal representative of a vehicle speed. A control unit is configured to carry out when, upon the transmission assuming the second speed, the vehicle speed represented by the vehicle speed signal becomes equal to or lower than a first predetermined speed, starting operation for fully releasing the engaged condition of the first clutch; when thereafter the vehicle speed becomes equal to or lower than a second predetermined speed that is lower than the first predetermined speed, starting operation for releasing the engaged condition of the second clutch; and when thereafter the vehicle speed becomes equal to or lower than a third predetermined speed that is lower than the second predetermined speed, starting operation for fully releasing the engaged condition of the second clutch and starting operation for engaging the first clutch from the fully released condition of the same.
